There is no such thing as a “PCI Compliant” cabinet.
There is no test that can be performed on a cabinet to allow it to be deemed 'PCI Compliant'.
PCI compliance for merchants states that they need to secure their networking and IT hardware that stores and transmits credit card data.
This means that they should lock it up, protect it, and be able to audit access logs to it.
With that in mind, any IT cabinet that’s secure on all accessible surfaces can help a merchant become compliant with the PCI standard.
